mb/google/zork: Disable ACP I2S wake for schematic version 3.6+
Starting with v3.6 of reference schematics, headphone jack interrupt
is moved to a standard GPIO instead of using CODEC_GPI. Thus, we no
longer need I2S wake to be enabled in the ACP for boards using v3.6+
version of schematics.
This change sets `acp_i2s_wake_enable` and `acp_pme_enable` to default
0 in baseboard devicetrees and overrides to 1 in update_hp_int_odl()
if the board is still using older version of reference schematics.
